I definitely feel it will blow up. The comic scene has never been stronger and a visual novel is a way for a comic to come to life just like vns due to mangasI agree, breh.
I've heard that the visual novels from Japan haven't penetrated into the western market as well as they have domestically because of certain stereotypes and tropes. I've heard of Fate Stay Night and a few others and maybe a light novel or two, but besides that, most of it doesn't attract me.
So I think your right when you say this is a market we could get into. It looks a lot less expensive than video games (which can always come later) and comics.
Actually, I myself would love to see more novels dealing with african alternative history.
